Abstract :
A 300 W and 100 kHz single phase soft switching power factor correction (PFC) circuit is developed with a new active snubber cell. This active snubber cell provides Zero Voltage Transition (ZVT) turn on and Zero Current Transition (ZCT) turn off for the main switch without any extra current or voltage stresses. The active snubber cell component values are defined by optimization process to minimize the switching losses of the PFC converter. As a result, this prototype has 98% total efficiency.
